Missing IE features in Opera

[funxus]

I just downloaded opera a week ago and . I like the bar below showing loaded pages and the fact that I don't have to see all the commercials popping up (I sometimes have 10 windows with the same commercial ) .
I have found two problems with this browser that works in IE:
1. Since I have broadband, I connect to internet by filling in username and password on a homepage. Then this page pop ups a window where I can log out.
First I would like my username and password to be filled in or shown in a list to easier log in, like in IE6. For the moment I have to fill in a long username and an odd password, which is hard to remember. Is this possible?
Second, the window where I can log out doesn't popup unless I change that option in preferences. I want to have certain servers where popups are available, is it possible?
2. I can't log in to my bank with opera, I can't download the certificates. I have chosen that the browser should say it's IE5 and not opera, but my bank still sense it. Are certificates possible to use in Opera, or do I have to use IE for this service?

Does anyone know how can solve these problems?

In answer to question 1 I'm pretty sure you can have Opera save your usernames and passwords, but I don't remeber how. I could check later.
About pop-ups, you can't stop only certain ones, for that you need a seperate program. (I just use the built-in features in Zonealarm Pro)

I found that I can put my username in the personal info, but I still have to write my password though. Before I bought a router I used zonealarm, but it slowed down mycomputer too much so I didn't keep it, now I have a firewall in the router.
